"I wanted it to be kind of dreamy and 1920s, when everything is soft focus. The Great Gatsby," she said. "The code name was GG for a while. That light and that kind of fun decadence. It's rock-n-roll Great Gatsby!"

"I've had big birthday parties, and I've thrown parties for other people, but this is a completely different thing. It's the Met Ball!

Jamie thinks I'm mad, asking, 'Are you gonna be all right? After the wedding, I'm hoping you'll get back to normal!'"
